SK Hynix, the company that makes the memory chips powering virtually every cutting-edge AI system on the planet, just laid out one of the most aggressive expansion plans the semiconductor industry has ever seen. The goal: triple its wafer production capacity by 2034.
SK Group Chairman Chey Tae-won disclosed the timeline in a Nikkei Asia interview, outlining a phased approach that starts with doubling capacity by around 2031 before reaching the triple mark three years later. Four new fabrication facilities at the Yongin Semiconductor Cluster in South Korea will anchor the effort, with the first cleanroom targeted for early 2027.
The numbers behind the buildout
The scale here is staggering. Phase 1 alone carries an investment tag of over KRW 21.6 trillion. And that’s just one piece of the puzzle.
In April 2026, SK Hynix separately committed roughly $13 billion to a new advanced packaging plant. That facility is designed specifically to meet demand for high-bandwidth memory, the specialized DRAM that sits atop AI processors from companies like NVIDIA and allows them to crunch data at speeds that standard memory simply can’t match.
